Another Ebay Seller trying to start a business. Account Limit.

I am new to Salehoo. And I would like to use the forum to get out of some doubt. I bought on eBay for many years.

Three months ago I started selling on Ebay products and my account is limited to selling 10 products a month.

I thought that the third month they'd get me to sell more than 10 products but that did not happen.

I have read and I see everywhere that the way to get more limits is calling them and asking to increase my limits.

My doubts are.

1. My native language is Spanish speak little English. they will have a helpline in Spanish? 2. What are the chances that they increase my limit? 3. What is the proper way to ask them the increase in case someone else has already done? 4. Approximately how much could be increased?
